Introduction

The partial discharge inspection instrument is a multifunctional handheld instrument. It is based on the detection methods of geomagnetic waves, ultrasonic waves, ultra-high frequency and high frequency currents. It can test the partial discharge of equipment, read the partial discharge amplitude and spectrum waveform, and provide two-dimensional and three-dimensional spectrum storage and readout functions, etc. It can better evaluate the partial discharge of electrical equipment. This instrument is suitable for partial discharge detection of electrical equipment such as GIS, switchgear, transformers and power cables. At the same time, it can observe the measurement signal in multiple cycles, identify the frequency of discharge, and analyze it through multiple modes to clearly judge the fault.
